Does raising speaker cables off the floor really make a big difference?

So here it is, Raising cables Works !
Large sound room,big system..lets tweek. Carefully suspended my cables from the ceiling using knob & tube technolog, as per the likes of John D.Harnden Jr. General Electric Engineer (Retired) and others. Strategically hung (clothes line style) cloth tapestries...Bingo Audio tweaking bliss ! Bored with the hunt scenes etc. down came the tapestries. Renovations gifted me a temporary cache of my girlfriends high end lingerie...Another Bingo, Visual & Audio stimulation !!
I'm minus a girl girlfriend & most of my female friends.
Further research left me tapestries on walls,wool area carpet,leather furniture,comfort and detailed audio sound. 
And finally my appropriate length wires / cables are separated as much as possible and on the floor !!
Research and knowledgable friends will save you money and aggravation dealing with scientifically baseless stupidity.
If given the opportunity look around at the wiring in a recording studio ...that'll make you smile.
Cheers

Makes zero difference.

Had a set under my cables for a couple of weeks now. It's made a huge difference. 

I spend time trying to stand them all back up every time I do anything around the system.

Right now I've found them most stable stack up on a shelf

What??

I think that rather than wondering if it makes a sonic difference, we should all be doing it to keep dust bunnies away from our expensive cables. Before I used the homemade ones that I now use I would have dust collecting all over them.
